FMRI

Full Definition

Functional magnetic resonance imaging (fMRI) is a neuroimaging technique that measures brain activity by detecting changes in blood oxygen level-dependent (BOLD) signals. This non-invasive method provides real-time visualization of brain function and is widely used in both clinical diagnosis and neuroscience research. Editorial contexts often require precise capitalization and hyphenation of related terms.

Usage

Usage note: Always capitalize when used as acronym; lowercase when spelled out unless beginning sentence.
